Smartphone-based Data Acquisition for Landslide Susceptibility Assessment
Abstract
The objective of this paper is to suggest a smartphone application for collecting geological data in the assessment process of landslide susceptibility. Spatial and geological information collection is the most crucial part in risk assessment while the evaluation of large area is often conducted using geographic information system (GIS). GIS-based landslide susceptibility assessment requires large database to ensure the reliability of analyses. The digitalized collection tool can help its users obtaining precise measurements and reducing time for the data collection process. In this study, the mobile application which measures structural information from inbuilt sensors and accepts various data types had been developed. It can collect the triggering factors that promote or inhibit the hazard occurrence in the training domain areas. The database includes various spatial information such as slope, aspect, joint set and their coordinates, as well as hazard inventory. Collected geospatial datasets with smartphone application can be applied to a series of geospatial processes regarding the assessment of the landslide susceptibility.
